When 18.9 kj is transferred to a gas sample in a constant volume adiabatic container with a calorimeter constant of 2.22 kj/k, the temperature of the gas (and the calorimeter) increases by 8.06 k. (a) what is the heat capacity of the sample? (b) if the sample has a mass of 0.5 kilograms, what is the specific heat capacity of the substance? (c) if the sample is krypton, what is the molar heat capacity at constant volume of krypton? the molar mass of krypton is 83.8 grams/mole.
